When connecting cameras to the HDMI input of the SOM-RK3399 dev kit my camera doesn't show up unless I set it to explicitly output 1080p. If the HDMI output resolution is set to "AUTO" it is not recognized. I'm assuming this is because there is no EDID support. Is this assumption correct? ...
My T4 and HD702E display came with some nice perspex mounting plates so it all goes together nicely. I then use a small cheap Chinese sourced CNC mill to cut out a front panel from 3mm acrylic and then use 3M VHB tape to secure it to the front panel. Works great.

I wasn't seeing anything on the camera preview. Turns out my camera was in Auto-Detect HDMI out mode. Changing it to output 1080p explicitly fixed my issue. But this brings up another question. Does the HDMI in port have EDID capability?
I am trying to use the HDMI input on the SOM-RK3399 in Android 8.1. Is this possible? I was under the impression that it would show up as the default camera in Android.
